Performance Results

The aim of this study was to explore students’ calibration of sport performance in relation to better or worse than average effect in physical education settings. Participants were 147 fifth and sixth grade students (71 boys, 76 girls) who were tested in a soccer passing accuracy test after they had provided estimations for their own and their peers’ performance in this test. Based on students’ actual and estimated performance, calibration indexes of accuracy and bias were calculated. Moreover, students were classified in better, worse, or equal than average groups based on estimated scores of their own and their peers’ average performance. Results showed that students overestimated their own performance while most of them believed that their own performance was worse than their peers’ average performance. No significant differences in calibration accuracy of soccer passing were found between better, worse, or equal than average groups of students. These results were discussed with reference to previous calibration research evidence and theoretical and practical implications for self-regulated learning and performance calibration in physical education.

AbstractWe describe the implementation and performance results of our massively parallel MPI†/OpenMP‡ hybrid TreePM code for large-scale cosmological N-body simulations. For domain decomposition, a recursive multi-section algorithm is used and the size of domains are automatically set so that the total calculation time is the same for all processes. We developed a highly-tuned gravity kernel for short-range forces, and a novel communication algorithm for long-range forces. For two trillion particles benchmark simulation, the average performance on the fullsystem of K computer (82,944 nodes, the total number of core is 663,552) is 5.8 Pflops, which corresponds to 55% of the peak speed.

The Relationship

Development of self-efficacy scales allows the analysis of athletes’ perceptions and examination of the relationship between perception and performance. The aim of this paper was to: (1) develop a specific self-efficacy scale in a taekwondo task, the roundhouse kick, and (2) analyse the sport performance and its relationship with two self-efficacy scales (specific and general) outcomes according to the athletes’ gender.<strong> </strong>Forty-three taekwondo athletes (33 male and 10 female) participated in this study. The Physical (PSE) and Specific (RKSES) self-efficacy scales were administered. Performance data (impact force and total response time) were acquired by athletes kicking twice to an instrumented target. Results showed that the specific self-efficacy scale has high reliability and is able to predict sport performance in males and females. Males had higher self-efficacy scores and also higher performance results than females. Females’ taekwondo psychological training should be focus on improving their self-efficacy perception in order to increase their performance in the roundhouse kick. This specific self-efficacy scale for the taekwondo roundhouse kick offers empirical information to coaches, sport psychologists and researchers that allow them to predict athletes’ sport performance in the roundhouse kick.

Stimulated Recall Interviews

The purpose of this study was to directly compare teacher and student expectations for task difficulty and performance, perceptions of actual task difficulty, perceptions of student performance and effort, and perceptions of teacher feedback. Stimulated recall interviews following a 14-lesson volleyball unit were conducted with 8 sixth-grade students and their physical education teacher. The results revealed little congruency between student and teacher perspectives of task difficulty or perceptions of student performance and effort. The students and the teacher agreed the most on expected performance level and the least on perceptions of effort. Such differences in perspectives may be partially explained by the sources of information used by the teacher and students to form their expectations and perceptions. There was somewhat higher agreement between the teacher and students on the purpose of and affective reactions to skill-related feedback.

The aim of this study was to test a method to assess the processes involved in mathematical problem solving, based on the Triple Task methodology and Self - Regulated Learning principles. This protocol was administered to 510 fifth and sixth grade students from Northern Spain, who carried out two mathematical tasks of varying difficulty. The results derived from the total sample indicated the presence of ineffective planning strategies and a lack of revision mechanisms. However, comparisons between groups with different achievement in the tasks revealed the sub - processes involved in planning (especially the use of representation strategies) as important determining factors in students' success rates, with these exerting a greater effect as task - difficulty increased.

This study aims to examine the level of confidence relationship with physical education learning achievement in elementary schools in the Tawang sub-district, Tasikmalaya City. The research method uses descriptive-correlational. The sample in this study is the sixth-grade students selected representing several schools in the District of Tawang as many as 60 students employing a purposive sampling technique. The instrument used was a confidential questionnaire. Data processing procedures to obtain answers about whether or not the hypothesis is accepted following the proposed significance are: (1) looking for averages, (2) looking for standard deviations, (3) testing normality through the Lillefors test (4) testing the correlation of two variables. Based on the results of research and statistical calculations on hypothesis testing the relationship of the level of confidence with physical education learning achievement, the authors can conclude as follows; there is a significant relationship between self-confidence and student achievement in class VI in Tawang District, Tasikmalaya City. Because the significance value obtained is greater than 0.05, and the value of Yxy (0.90)> (0.250) rtable (0.05) (60) then H0 is rejected and Ha is accepted, so there is a significant relationship between self-confidence and achievement learning (significant).
